Blizzard posted a blog about upcoming celebrations of 20 years of Diablo across their franchises, including World of Warcraft. We already have some datamined items that seem to be related to a Diablo event in WoW, and there has been some speculation that the Treasure Goblins we saw during Legion's beta test will possibly be back!

With Leaderboards up, players can check them to see how these elite guilds stack up on stage against the record times currently established around the world.

We have our team at BlizzCon down in Anaheim and some of us are watching the stream at home. We're bringing you the latest and liveblogging the opening ceremony plus the World of Warcraft panels. Since this is the first BlizzCon without leaks, this should be a pretty huge opening--it's confirmed there will be a new expansion for World of Warcraft, but it also looks like there will be tons of new other announcements.

Make sure to join in the discussion here in this post as if you're watching along on the stream.

So things just got really serious--4.3, which was a huge mystery, is now pretty much unveiled at Gamescom. When speaking to Kotaku and Gamona.de, Tom Chilton was very open in just how much content the patch would have for WoW players. " has a whole bunch of content," he said, "three dungeons for five player instances and a new raid instance culminating in the Deathwing fight."

Of course, it's not just dungeons to be excited for. Those ethereals we mentioned a week and a half ago? They're for what most of us only dreamed in our biggest dreams and Blizzard previously said was impossible: armor customization. "We have a wealth of armor sets we created that people no longer use," Chilton said, explaining why they had chosen to add it in.

What we know about 4.3:Deathwing in 4.3According to Kotaku: "The Deathwing fight will be the most epic boss encounter to date, including a battle phase that takes pla

This week we got our hands on some footage of an incredible SC2 mod called, "World of Starcraft" and it looks like since the show, Activision has ordered that all the trailers be removed from YouTube, a classy move, of course. We also covered the latest PTR changes as well as some silly drama between the top raiding guilds.

Today, Blizzard posted a quick note to mention that they'll be AFK from the forums for a bit enjoying their holidays. They've also announced the winners of the Your Fortune Awaits video and print ad contests and are even sharing some holiday cheer in the form of new seasonal card art! Also, there's a quick blue note regarding changes to arena ratings and item requirements.

Just the latest news from the world of Blizzard, including a small batch of Cataclysm hotfixes, veiled details about Blizzard's new MMO, tips on surviving Heroics and more!

Notable Cataclysm hotfixes include:

The search radius to find an Archaeology node from the Archaeology ability Survey has been increased. This will result in fewer searches needed while in the "green" range of surveying.

Chakra is no longer consumed by a Prayer of Mending bounce.

Several shirts have been corrected so they no longer cause a player's item level to increase. They are item level 1.

In addition, another, undocumented hotfix was recently applied which will make it so that players without an appropriate crafting profession of 425 or higher will no longer be able to 'Need' roll on Chaos Orb! This should be a welcome change for any users with the profession, however I still say that making them BOP was silly in the first place. But meh, we're probably just a few patches away from a change on that - and by then, it won't matter.

A hotfix was applied about an hour ago that changes it so Chaos Orbs will only be available
